Neural Network Beamforming Technique for Cyclostationary Signals

Most of the communication signals have the cyclostationary character. SCORE is an excellent algorithm based on cyclostationary. However, main disadvantage of this algorithm is the huge calculation of the matrix compution and the matrix inverse compution. A neural network beamforming technique which can solve this problem successfully is proposed in this paper. The experiment results have shown that this algorithm has better performance and can reject noise strongly.
